Process for preparation, cutting, and sorting of lamellas into band of insulation filling, preferably mineral wool used as light building panels filling characterized in that it comprises removal of insulation filling slabs, cutting of insulation filling slabs into lamellas, characterized in that includes transport of pallets accumulation of said lamellas, guiding of said lamellas into a band of said lamellas, formation of repeatability of frontal coupling contour of said lamellas, profiling of sides of said band of said lamellas, and transport of said lamellas between steps in said process. 3. Process according to claim 1 characterized in that cutting is achieved using a band saw (164). 4. Process according to any of preceding claims characterized in that said insulation filling slabs, preferably mineral wool, are cut into said lamellas in a vertical position. 5. Process according to any of preceding claims characterized in that a system of transporters provides for sufficient accumulation of said filling on the operation line in an amount sufficient to enable change of type of filling and/or saws without stopping of said operation. 6. Process according to any of preceding claims characterized in that the lamellas are stored in a repository or plurality thereof in separated compartments separating one from another to descend onto conveyer belt. 7. Process according to any of preceding claims characterized in that formation of desired displacement between adjacent lamellas is performed at a point on said production line for manufacturing of said light building panel immediately prior to pressing of the lamellas into the band of the lamellas and immediately after ending of separating guide walls (115), and that so formed band of said lamellas is fixed by pressing said lamellas from the sides of the band of the lamellas using side conveyer belts (114), and pressed from above and/or below with separately driven conveyer belts(112) with momentum control/and or regulation. 8. Process according to any of preceding claims characterized in that the device for profiling of the band of the lamellas side (120) is comprised of saws and/or milling tools and/or other cutting tools and is controlled with mechanism enabling change of setting according to change of light building panel thickness during operation of production line. 9. Process according to any of preceding claims characterized in that the band of the lamellas is pushed by regulated force and/or features electronically regulated system of guidance over the inflection, said arrangement providing for side guidance and friction between the lamellas preventing hoarding of the lamellas and/or break-up of the band of the lamellas. 10. Process according to any of preceding claims characterized in that an elastic deformation of the lamellas (the band) is taken advantage of in a lengthwise direction in order to prevent vertical displacements between the lamellas due to the inflection, and boundary displacement in the area in which the band is not supported due to movement of glue sprayer head. 11. Apparatus for preparation, cutting, and sorting of lamellas into band of insulation filling, preferably mineral wool used as light building panels filling characterized in that it comprises transport means for transport of insulation filling slabs toward removal means, said removal means for removal of said insulation filling slabs, cutting means for cutting of said insulation filling into lamellas, separation means for separating of stack of said lamellas into individual lamellas already turned in such direction that fibres in said lamellas are in vertical direction and said lamellas themselves oriented in lengthwise direction along direction of band of said lamellas preventing need for turning of each said lamella, accumulation means for formation of accumulation of said lamellas during operation of a production line for manufacturing of light building panels to allow for change of dimensions of manufactured light building panels or change of tools without stopping or with minimum stopping time of said production line, means for formation of repeatability of frontal coupling of said lamellas, and transport means for transport of lamellas between phases of said process connected thereto. 12. Apparatus for preparation, cutting, and sorting of lamellas into band of insulation filling, preferably mineral wool used as light building panels filling characterized in that it comprises a device (10) for removal of insulation filling slabs from pallets loaded with said insulation filling slabs, a device (100, 166) for delivery of said lamellas said device comprising at least one compartment, mechanism (113) for formation of initial desired lengthwise displacement between adjacent lamellas, and conveyer belts for transport and guiding of said lamellas. 13. Apparatus according to claim 12 characterized in that said apparatus for cutting is a band saw (164). 14. Apparatus according to claim 11 characterized in that the transport means comprise an input transporter of line A(1), an accumulation transporter of line B (2), an accumulation transporter of line C (3), a cart (4), a transporter of line E (5), a transporter of line D (6), a cart (7), pallet palletizer (8). 15. Apparatus according to any of the claims 11 to 14 characterized in that the transport means provide for at least one transporter onto which the pallet with remainder of insulation filling slabs is being loaded following change of insulation filling slabs with dimensions differing from ones input into production line. 16. Apparatus according to any of the claims 11 to 15 characterized in that the removal of insulation filling slab or plurality thereof is achieved by side conveyer belts (12) operating in pair or plurality of pairs by said pair of side conveyer belts (12) engaging said insulation filling slab or plurality thereof by means of friction and transporting said insulation filling slab or plurality thereof to vertical transporter with rods (13), and disengaging said insulation filling slab or plurality thereof after the transport to said vertical transport with rods (13) has been completed by moving said paired side conveyer belts (12) apart from one another. 17. Apparatus according to any of the claims 11 to 16 characterized in that the cutting is achieved using circular saw arrangement (41) with plurality of circular disks spaced apart in order to achieve desired lamella height mounted on single axle which can be swiftly exchanged for another circular saw arrangement with different spacing between cutting disks. 18. Apparatus according to any of the claims 11 to 17 characterized in that the cutting is achieved using band saw (164) whereby said band saw (164) cuts plurality of insulation filling slabs suspended in vertical position using lifting frame (162) while said band saw (164) is guided with sawing band guides between each adjacent slab said arrangement diminishing bending/curving of sawing band. 19. Apparatus according to any of the claims 11 to 18 characterized in that there are repository of said lamellas or plurality thereof provided so said production line for manufacturing of said light building panels can operate without stopping the production of said light building panel while insulation filling slabs of different dimensions as compared to ones undergoing the production process are being loaded or cutting tools are being exchanged. 20. Apparatus according to any of the claims 11 to 19 characterized in that the device for profiling of the band of the lamellas side (120) is comprised of saws and/or milling tools and/or other cutting tools and is controlled with mechanism enabling change of setting according to change of light building panel thickness during operation of production line. 21.
